5 minute sex

I love my husband and our sex life. He always makes sure I get lots of foreplay, but I like actual sex. The longest he’s ever lasted (and this was from start to finish with two orgasms) was 10 minutes at the most. I’m wondering if maybe there’s something wrong going on down there? We’ve been having sex for about 3 years and we’re trying for a baby so we’re having sex every other day and he still only lasts 5ish minutes if he cums once. Just wondering if any girls can relate? I just wish I could have his dick longer 😂
